Hi Mathias, I am working on running our custom USB dual-role product through some compliance testing. It seems that the SoC and host controller are not responding to the LFPS signaling and timeout that is supposed to automatically begin the compliance test sequence. I'm currently running a 4.9.115 kernel, and I'm afraid I might be missing some critical patches for compliance test support. I noticed these two patches came up in a google search: https://patchwork.kernel.org/patch/10415345/ https://www.spinics.net/lists/linux-usb/msg160002.html Besides these patches, is there anything else that comes to mind that I might need to do to start compliance testing? I'm about to build a more recent kernel to see if that improves my situation as well. Just for reference, our product uses an intel atom z8550 SoC that uses an xHCI host controller and a dwc3 device controller. Our platform also uses a USB 3.0 redriver. The datasheet for this redriver (tusb542) indicates that it's internal LFPS controller supports full USB 3.0 compliance requirements. Thanks in advance for your guidance! Cheers, Rob Weber
